Description

Technical Field

[0001] This utility model relates to the field of sorting machine technology, and in particular to a multi-functional sorting machine. Background Technology

[0002] In the FPC (Flexible Printed Circuit) production process, sorting is a core step in ensuring FPC shipment quality and preventing defective products from reaching customers. Its effectiveness directly and critically impacts product yield and customer satisfaction. Currently, FPC sorting primarily employs manual inspection. Operators meticulously inspect the appearance and key dimensions of each FPC using visual observation or auxiliary tools such as magnifying glasses and microscopes.

[0003] However, this traditional manual sorting method has revealed many obvious drawbacks. On the one hand, manual inspection is inefficient and slow, making it difficult to meet production schedule requirements in large-scale mass production scenarios. On the other hand, manual inspection is limited in its ability to detect minute defects. For example, defects such as minor circuit damage, micropore blockage, and micron-level dimensional deviations are often difficult to identify accurately by manual inspection, easily leading to missed detections and misjudgments. This undoubtedly negatively impacts the accuracy of sorting, thereby compromising the consistency of product quality. Utility Model Content

[0004] Based on this, the present invention provides a multi-functional sorting machine with a simple structure and convenient use. The material handling components have three-axis motion directions. By utilizing the synergistic effect of the suction cup claw, CCD camera, and lifting platform, FPC products can be automatically detected and sorted, which greatly improves sorting efficiency and quality, effectively avoids missed detection and misjudgment, and further ensures the consistency of product quality.

[0018] Please see Figures 1 to 5 The multifunctional sorting machine according to one embodiment of the present utility model includes a carrying component 10, a material handling component 20 installed inside the carrying component 10, a vision inspection component 30 installed inside the carrying component 10, multiple lifting platforms 40 installed inside the carrying component 10, and a hopper 50 installed on one side of the lifting platform 40.

[0019] The supporting component 10 includes a body 11 and a cover 12 installed on the top of the body 11.

[0020] The material handling assembly 20 includes a Y-axis linear module 21 installed inside the machine cover 12, a two-axis manipulator 22 connected to the Y-axis linear module 21, and a suction cup claw 23 installed at the end of the two-axis manipulator 22; wherein, the two-axis manipulator 22 has dual-axis movement directions in the X-axis direction and the Z-axis direction.

[0021] Specifically, such as Figure 3 As shown, the two-axis manipulator 22 includes a slide cylinder 221 connected to the Y-axis linear module 21 and arranged along the X-axis direction, and a lifting cylinder 222 connected to the sliding part of the slide cylinder 221; the lifting cylinder 222 moves along the Z-axis direction. The suction cup gripper 23 includes a support plate 231 connected to the end of the lifting cylinder 222, and a plurality of suction cups 232 evenly spaced on the bottom surface of the support plate 231.

[0022] The vision inspection component 30 includes a fixed beam 31 fixedly installed inside one side of the machine housing 12, a cross slide module 32 connected to the fixed beam 31, a CCD camera 33 connected to the cross slide module 32, a magnifying lens 34 coaxially connected to the CCD camera 33, and a ring light source 35 coaxially installed below the magnifying lens 34. The vision inspection component 30 is located above the material handling component 20 to avoid interference and collision between the two during operation.

[0023] In this embodiment, the cross slide module 32 has bidirectional adjustment directions for the X-axis and Z-axis.

[0024] The lifting platform 40 includes a lifting cylinder 41 installed inside the body 11, a platform 42 connected to the lifting cylinder 41, and an infrared ranging sensor 43 located on one side of the platform 42; the optical window of the infrared ranging sensor 43 is set facing the platform 42.

[0025] In this embodiment, the infrared ranging sensor 43 is mounted on one side of the platform 42 via a surrounding plate 44, with the surrounding plate 44 being adjacent to the platform 42.

[0026] In this embodiment, there are four lifting platforms 40, which are arranged in a matrix. Figure 5 As shown, for easy differentiation, the four lifting platforms 40 are respectively labeled as: inspection lifting platform 40, OK product placement lifting platform 40a, release paper placement lifting platform 40b, and NG product placement lifting platform 40c. The inspection lifting platform 40 and the release paper placement lifting platform 40b are arranged diagonally, as are the OK product placement lifting platform 40a and the NG product placement lifting platform 40c. The inspection lifting platform 40 is located directly below the visual inspection component 30 to facilitate inspection by the CCD camera 33.

[0027] The hopper 50 is installed on the top surface of the machine body 11. The hopper 50 has multiple placement chambers 51 evenly spaced inside, which can be used to place FPC products of different testing categories, such as OK products, NG products with line damage, NG products with micropore blockage, or NG products with dimensional deviation. By placing various types of FPC products in different categories, it is convenient to recycle and repair them later.

[0028] During actual sorting, a manual person places a stack of FPC products (with release paper between each FPC product) onto the inspection lifting platform 40. The CCD camera 33 begins detection and analysis. After receiving the corresponding instructions, the material handling assembly 20 moves the suction cup claw 23 above the inspection lifting platform 40 via the Y-axis linear module 21. The two-axis robotic arm 22 drives the suction cup claw 23 to fall and pick up the FPC product. After the FPC product is removed, the lifting cylinder 41 drives the platform 42 to automatically rise one unit stroke (i.e., the thickness of one FPC product) according to a predetermined program, ensuring that the next FPC product to be inspected reaches the specified inspection height, that is, meets the depth of field requirements of the CCD camera 33, thus ensuring the normal operation of the visual inspection. Next, based on the inspection results, the Y-axis linear module 21 and the two-axis robotic arm 22 drive the suction cup claw 23 to place the FPC product into the corresponding placement chamber 51. After the FPC products are placed, the Y-axis linear module 21 drives the suction cup claw 23 back above the inspection lifting platform 40. The two-axis robotic arm 22 drives the suction cup claw 23 to fall and pick up the release paper, placing it on the release paper placement lifting platform 40b. At this time, the lifting cylinder 41 of the release paper placement lifting platform 40b drives the platform 42 to automatically descend one unit stroke (i.e., the thickness of one release paper) according to a predetermined program, facilitating the next reception of release paper. This completes the sorting operation for one FPC product. Repeating this process achieves automatic sorting.

[0029] Furthermore, the multi-functional sorting machine of this utility model also includes a temporary storage plate 60 connected to the side of the lifting platform 40 facing away from the hopper 50. The temporary storage plate 60 is used in conjunction with the OK product placement lifting platform 40a and the release paper placement lifting platform 40b to realize the palletizing function.

[0030] The working process is as follows: First, a whole stack of sorted OK products is placed on the temporary storage plate 60, and a whole stack of release paper is placed on the release paper placement lifting platform 40b. At the start of the operation, after receiving the corresponding instruction, the material handling component 20 moves the suction cup claw 23 above the temporary storage plate 60 via the Y-axis linear module 21. The two-axis robotic arm 22 drives the suction cup claw 23 to fall and pick up the OK products, which are then transferred to the platform 42 of the OK product placement lifting platform 40a. Next, the lifting cylinder 41 of the OK product placement lifting platform 40a drives the platform 42 to automatically descend one unit stroke (i.e., the thickness of one FPC product) according to a predetermined program, facilitating the next reception of OK products. Then, the material handling assembly 20 moves the suction cup claw 23 above the release paper placement lifting platform 40b. The two-axis robotic arm 22 drives the suction cup claw 23 to descend and pick up the release paper, which is then transferred to the OK product placement lifting platform 40a and placed on top of the OK product. This avoids direct contact between the next OK product and an already placed OK product. When removing the release paper, the lifting cylinder 41 of the release paper placement lifting platform 40b drives the platform 42 to automatically rise one unit stroke (i.e., the thickness of one release paper) according to a predetermined program, facilitating the next use of the release paper by the suction cup claw 23.

[0031] The aforementioned multi-functional sorting machine has a simple structure and is easy to use. The material handling component 20 has three-axis motion direction. By utilizing the synergistic effect of the suction cup claw 23, CCD camera 33, and lifting platform 40, it can automatically detect and sort FPC products, greatly improving sorting efficiency and quality, effectively avoiding missed detections and misjudgments, and further ensuring the consistency of product quality.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
